IPF8000 printing with faint grey lines

Hello everyone,

My Canon ipf8000 is printing with faint grey lines across the width of every print.

I've attached an image here of what i mean:

I have replaced the Left Printhead (contains black and greys) mutliple times. I have also replaced the Flexible Cable Assembly and the Printhead Relay PCB.

I have also ordered a Carriage Relay PCB and a Linear Scale.

I have done every calibration possible, and these lines just appear on all print.

I thought it might be a head crashing issue, but head height is set to Highest and paper vacuum strangth is set to strongest.

I have also cleans the carriage and the underside of the printheads.

Does anyone have any ideas?

Many Thanks

Marcus

 

Hi Marcus,

I have the same issue with an ipf8000, did you resolve the problem?

thanks

Hi Gareth,

In the end, i had to change the Main Board PCB, as everything else did not fix the issue.

But changing the Main Board sorted it. I think it was defective as it was a second hand board anyway.

Good Luck

 

OK, thanks, and thank you for your quick response.
